The Triumph Register of America began life in May 1974, as the Triumph TR-3 Sports Car Club of Central Ohio.

Enough interest was generated in this regional club to bring about a change of name to Triumph Register of America, an organization with a national focus. Shortly thereafter, TRA was recognized by British Leyland through its Triumph Sports Owners Association, and is also formally affiliated with the British TR Register which was similarly formed to preserve the TR2-3 series.

TRA is a non-profit organization established to aid TR2, 3, 3A, 3B, 4, and 4A owners in the preservation, maintenance and enjoyment of their classic sports cars and is concerned with establishing local groups of TR2, 3, 3A, 3B, 4, and 4A owners. We believe that local used parts supply networks and local activities such as technical workshops or rallies provide the binding glue for our National organization. TRA is firmly a grassroots organization, which offers many advantages and services for individual members, groups, and local centers.
